HINGE Filed March 2, 1964 2 Sheets-Sheet 2 United States Patent 3,267,611 HINGE George C. Hayman, 2350 E. Ilitf, Apt. 9, Denver, Colo. Filed Mar. 2, 1964, Ser. No. 348,613 2 Claims. (Cl. 49-251.)

The present invention relates to a novel window structure and more specifically to hinge means for mounting an awning type sash in a window structure.

An important object of the present invention is to provide a novel awning type window structure including hinge means of simplified and relatively economical construction.

A further important object of the present invention is to provide a novel awning type window structure having hinge means constructed for facilitating assembly of a sash with a frame and also removal of the sash for cleaning or any other desired purpose.

Still another important object of the present invention is to provide a novel awning type window structure having hinge means constructed for supporting the sash in a manner for minimizing wear on weather stripping during opening and closing of the sash while at the same time assuring an effective seal between the sash and the window frame when the sash is fully closed.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings, wherein:

FIG. 1 is a perspective view showing a window structure incorporating features of the present invention with the sash fully closed;

FIG. 2 is a perspective view of the window structure with the sash opened;

FIG. 3 is an enlarged sectional view taken generally along line 33 in FIG. 2;

FIG. 4 is an enlarged fragmentary view taken along line 44 in FIG. 1;

FIG. 5 is a perspective view showing a sash with portions of a hinge structure incorporating features of the present invention connected thereto;

FIG. 6 is an enlarged fragmentary sectional view taken along line 6-6 in FIG. 1;

FIG. 7 is an enlarged fragmentary sectional view taken along line 77 in FIG. 5; and

FIG. 8 is a further enlarged fragmentary sectional view similar to a left-hand portion of FIG. 4 and showing parts of the structure in greater detail.

Referring now more specifically to the drawings, wherein like parts are designated by the same numerals throughout the various figures, the window structure 10 incorporating features of the present invention comprises a rectangular frame 12 and a rectangular sash 14. The frame 12 comprises horizontal header and sill members 16 and 18, respectively, which are connected by upstanding opposite side members 20 and 22. The sash also includes horizontal upper and lower members 24 and 26 and upstanding side frame members 28 and 30.

Hinge means 32 and 34, constructed in accordance with features of the present invention described in detail below, are provided between opposing pairs of frame and sash side members 20-28 and 22-30 for supporting the sash for movement between the closed position shown in FIG. 1 and the open positions shown in FIGS. 2 and 3. Upper and lower stop members 36 and 38 are, respec- =tively, secured to the header and sill members 16 and 18 of the frame and similar side stop members 40 and 42 are secured to the side frame members 20 and 22 for limiting inward pivotal movement of the sash. As shown best in FIGS. 4 and 8, resilient weather strips 44 are secured to the outwardly facing surfaces of all of 3,267,511 Patented August 23, 1966 the stop elements for engaging the sash when the sash is closed and providing a weathertight seal.

Various known means may be provided for manipulating the sash between the open and closed positions. In the embodiment shown, this means comprises a push bar 46 extending through a fitting 48 mounted to and providing an opening in the lower stop member 38. An outer end of the push bar is pivotally connected by pin 50 to a link 52 which in turn is connected by a pin 54 to a bracket 56 secured to the bottom horizontal member of the sash. The arrangement is such that when the push bar 46 is manually manipulated so that it is substantially axially aligned with the link 52 and bracket 56, the push bar may be axially shifted through the fitting 48 for opening and closing the window. When the window is fully closed, as shown in FIG. 1, the link 52 projects partially through the fitting 48 so that the pin 50 is located inwardly of the fitting whereby the push bar 46 may be pivoted to a position extending parallel to the stop member 38 and interengaged with a latch member 58 for locking the window.

The hinge means 32 and 34 are identical but oppositely disposed and, therefore, identical reference numerals will be applied to corresponding elements. Each hinge means comprises a first straplike element 60 secured to an outwardly facing surface of an upstanding side member of the sash. Each element 60 has a lower end portion thereoffixed by a plurality of screws 62 to the sash member, while an upper end portion 64 normally flares outwardly from, and is laterally offset from, the sash side member, as shown best in FIG. 7. A pivot and slide block 66 is connected to and projects outwardly from the upper end of the hinge portion 64 and it is to be noted that the hinge portion extends sufliciently above an upper edge 68 of the sash so that the axis of the pivot and slide block 66 is above the edge 68.

Each hinge means includes a second straplike element or strut member 70 having one end pivotally connected by pin 72 to a lower end portion of the hinge element 60 and preferably between the screws 62. The hinge element 70 extends downwardly from the pivot pin 72 and is formed so that it normally bows outwardly from the side of the sash as shown best in FIG. 7. A second pivot and slide block 74 is secured to a lower end of the hinge element 70.

The hinge means 32 and 34 also respectively include vertically disposed generally U-shaped channel members 76 mounted in vertically extending grooves 78 provided in the opposite side frame members 20 and 22. The channel or track members 76 have a generally U-shaped cross-sectional configuration and provide side flanges 80 and 82 as shown best in FIGS. 3, 4 and 8. When the structure is fully assembled, the pivot and slide blocks 66 and 74 of the hinge means project into the slots defined between flanges 80 and 82. Furthermore the spacing between the side edges of the sash and the channel or track members 76 is less than the distances which the upper and lower ends of the hinge members 60 and 70 and the pivot and slide elements 66 and 74 thereon are spaced from the sash whereby the upper and lower end portions of the hinge elements 60 and 70, respectively, will be deflected toward the sash when the pivot and slide blocks 66 and 74 are assembled with the track members. The hinge elements 60 and 78 are formed from a resilient or spring material such as steel so that the inherent resiliency thereof continuously urges the pivot and slide blocks into proper engagement with the tracks. The force with which the pivot and slide blocks are urged against bottom walls 84 of the channel or track member 76 causes sufiicient frictional resistance to movement of the slide blocks along the track members so that the window sash will be efiectively retained in any desired partially open position to which it may be adjusted. However, the pivot and slide blocks are formed from a suitable bearing material, including plastic material such as nylon, for assuring easy opening and closing of the sash when an operator manipulates the push bar 46.

As indicated above, the pivot and slide blocks 66 of the hinge means 32 and 34 are disposed so that their common axis is located above the uppermost edge 68 of the top sash member 24. As a result of this arrangement, pivotal movement of the sash about the axis of the element 66 from a closed position to an open position causes an upper and inner corner 3-5 of the top sash member to swing immediately outwardly from the Weather stripping. In other words, the corner 36 of the sash Will avoid engagement with and wear on the weather stripping during all pivotal movement of the sash and will be drawn against the weather stripping only when the sash is substantially fully closed.

It has been found that with the hinge structure described above, the sash may be quickly and easily as sembled with and removed from the window frame. For example, during installation, the sash is held in an inclined position similar to the open position shown in FIGS. 2 and 3 and the upper sash member 24 is positioned between the opposite sides of the frame. Then the sash is manipulated so that the upper frame member is inclined from the horizontal with one end thereof lower than the other, whereupon the pivot and slide blocks 66 of the hinge means 32 and 34 may be positioned between the opposing track members. When this has been accomplished, the sash is again manipulated so that the upper member 24 thereof extends horizontally between the track members. The lower element 70 of the hinge means may then be readily manipulated so that the pivot and slide blocks 74 thereon are interengaged with the track members. Of course this process can be easily reversed for removing the sash from the frame.

While a preferred embodiment of the present invention has been shown and described herein, it is obvious that many details may be changed without departing from the spirit and scope of the appended claims.
